Remotes

The remote controls for Fiat vehicles look similar to the keys, but they feature an IR (infrared) LED on the top. The LED sends a digital signal to the device that opens or turns off the vehicle when the button is pressed. The microprocessor in the key converts the signal into a number that is then transmitted to the device.

This method is referred to as "keyless entry". The more modern your vehicle, the more likely to have a keyless entry feature. The more advanced your car has, the more features it will come with. This includes locking and unlocking your car with just one touch or opening the doors without touching the handle, and much more.

The key fob is fitted with an integrated circuit chip that communicates with the immobiliser system in the car. The system determines whether the key is working by examining a specific sequence of the transponder. If the chip isn't present, or if it is not programmed to the correct immobiliser system, then the vehicle will not start.

A locksmith can repair the key fob if it's damaged. They'll also have to program the replacement key to connect with the vehicle's immobiliser. This is a crucial aspect of the procedure, and you should be prepared to disclose information about your vehicle to the locksmith if they contact you.

Keyless Entry

If you have a keyless entry system on your Fiat 500, you can lock and unlock the vehicle from any location with the click of one button. This technology is becoming more prevalent in all cars of all kinds and ages as it provides convenience and safety to the vehicle's usage.

If your remote keyless entry system fails to work look to see if the coin battery in the fob has gone dead. If the battery is drained replace it with a new one that is of the same size, voltage and type as the original. It is also important to ensure that the battery's contacts are free of dust or corrosion.

The rubber seals on the key fob guard the chip from water. However, prolonged exposure to salty or soapy water can cause the chip to fail. If your key fob has been exposed to water, take it out and let the battery dry completely before replacing it. You can also clean the electronic chip with isopropyl and electronic cleaner.

While some may believe that keyless entry isn't as secure, the system is actually more secure than traditional systems due to the fact that the code that unlocks your car is rolled up after each use. This means that even if hackers attempt to intercept the signal that they receive, they will not be able to gain access to your vehicle.

Transponders

Fiat uses a crypto key transponder, which means that keys/transponders have to be encoded with a secret code by the Body Control Module (BCM) before being "programmed" into the BCM. This is why an unwritten key is not able to be programmed, because the BCM has to read & write its secret key to the transponder and then lock it. This is referred to as cloning.

These are brand new replacement outer cases that replace the SIP22 Transponder keys for Fiat 500. They have a chip inside that opens the doors and also starts the car. They will need to be cut professionally by a locksmith to fit your ignition.
